Good rhythm and flow on a golf course is like good theater – there is a series of acts that build upon one another to create a sum greater than its parts. The rhythm and flow is critical to creating a good golf course experience because great holes that don’t connect and flow together won’t “complete” a course like a good sequence of holes can.
The great courses of the world, whether they are links like Royal Dornoch or an inland course like Augusta National, have great rhythm and flow and world-class holes that make them desirable to play every day. Certainly there are many non-famous courses that are fun and challenging for their players on a regular basis – that may be the true meaning of good rhythm and flow.
